Specification of Letters Patent.

Patented Dec. 23, 1916.

Application filed January 29, 1914. Serial No. 815,114.

To all whom it may concern Be it known that I, MORRIS RAKowsKr, acitizen of the United States, residing at Utica, in the county of Oneidaand State of New York, have invented certain new and useful Improvementsin Gearing, of which the following is a specification.

My invention relates to improved gearing means particularly spring-motoractuated, designed especially for operating a fan.

The invention aims to provide apparatus highly effective for itspurposes employing novel gearings, novel means for regulating the speedof rotation of the parts, and novel means for maintaining and drivingthe fan in an inclined plane.

In the accompanying drawings, one form of the device is illustratedwhich comprises parts that are substantial, will prove durable in use,forming a device that may be manufactured at minimum cost.

With respect to said drawings: Figure 1 is a vertical sectional view;Fig. 2 is a fragmentary view partly in plan and partly in section. Fig.3 is a partial side elevation illustrating the pivotal connection of thesections of the standard; Fig. 4 is a detail view illustrating thevertical shaft sections at angular adjustment, and Fig. 5 is afragmentary elevation specifically illustrating the winding shaft in endelevation.

Referring specifically to the drawing, a casing or housing is employedcomprising a base section 1, on which is rigidly fastened a plate orintermediate section 2 made separate therefrom and an upper section 3made separate from the other sections and rigidly fastened to thesection 2. Section 1 has a horizontal wall 4 which divides it into twocompartments the upper of which contains an actuating motor, in the formof a clock spring 5 fastened to operate a vertical short shaft 6rotatably mounted in the section 2 and wall 4 and having keyed theretoat its upper end beyond section 2 a spur gear wheel 7 and keyed theretoat its lower end beyond wall 4 a bevel gear wheel 8. The lower of thecompartments of section 1 has a bearing 9 in which is rotatably mounteda winding shaft 10 having keyed thereto a bevel gear wheel 11 in meshwith the gear wheel 8. Said shaft 10 has a winding key engaging shank12, preferably polygonal in cross section arranged adjacent a key insertopening 13 of the section 1.

On the section 2 is rotatably mounted a gear plate 14 having an annularrack 15 provided with beveled teeth. This plate 14 preferably travelsdirectly on rollers 16 mounted in an annular bearing 17 on section 2.The plate has a depending stud 19 rigid therewith and the stud 19 isrigid with a disk 19 having teeth engaging those of a gear wheel 7. Theelements 19 and 19 do not move relatively to the plate 14.

Depending from the top wall of the upper casing section are bearingbrackets 20 in which are journaled preferably at an angle, one or moreshafts 21 which have keyed thereto gear wheels 22 in mesh with the teethof the rack 15. Bevel gear wheels 23 are keyed to shafts 21 and meshwith a bevel gear 24 carried by a vertical shaft 25. The disks areadapted to be engaged by brake shoes or levers 28 in order to arrestcompletely or partially motion of the shafts and also of the spring 5,and entire apparatus. Said levers are pivoted at 29 to the top wall ofsection 3 and extend through enlarged openings 30 therein. A connectingrod 31 is pivoted to said levers and to a link 32 pivoted to anoperating lever 32 and adapted to lock to a toothed segment 33 on saidtop wall of section 3. Shaft 25 is journaled in bearing plates 34 of asection 35 of a standard or post rigidly fastened on section 3. A gearclutch member or wheel 36 is keyed on shaft 25 and cooperating therewithis a similar gear and clutch wheel 37 mounted on a shank or hollow shaft38 mounted to slide on and rotate with a shaft 39 to this end havingribs 40 extending in longitudinal grooves 41 of the shaft. A second postor standard section 42 is pivotally mounted on the section 35 by plates43 adjustably fastened together by a bolt 44 having a clamping set screw45 thereon. A cap casing 46 is removably clamped on section 42 by walls47 and a set screw 48. Shaft 39 has fastened thereto a bevel gear wheel49 meshing with a bevel gearwheel 50 keyed on a shaft 51 mounted in thecap casing and adapted to carry thereon a fan such as shown at 52.

In operation, shaft 10 is turned by a key applied at 12 and the spring 5wound, and may be maintained wound and inactive by proper friction tightengagement of the levers 28 with disks 27 through shifting of lever 32.When the fan 52 revolves the levers 28 are disengaged fro-m tightrelationship With the disks 27 whereupon the spring turns shaft 6, andgear 7, the latter engaging gear 19 but turns shaft 19 and plate 15, thelatter traveling on the rollers 16. In turn rack 15 drives gears 22,shafts 21, gears 23 and 24, shaft 25 and gears 36 and 87 and shank 41.If the fan is desired to turn at an angle, nut 45 is loosened and thepost section 42 turned to the proper angle and simultaneously shaft orshank 41 Will be shifted as seen in Fig. 4 and will slide a properextent on shaft 39. Then the nut 45 is tightened. Shaft 39 drives gears49 and 50, the latter driving the shaft 51 and fan 52 thereon.

Changes may be made in the details of construction Without departingfrom the spirit and scope of the invention.

I claim:

1. Apparatus of theclass described having a driven gear Wheel, a gearplate, a driving member on said plate in mesh With said gear Wheel and ashaft driven from said plate, and means to mount said plate forrotation, comprising a bearing and said plate having means overlappingand engaging said bearing to prevent displacement.

2. Apparatus of the class described having a driven gear Wheel, a gearplate, a driving member on said plate in mesh With said gear Wheel and ashaft driven from said plate and means to mount said plate for rotation,comprising an annular bearing, rollers on said bearing on Which saidplate rests and a Wall depending from said plate overlapping andsurrounding said bearing to prevent displacement.

3. Apparatus of the class described having a driven gear member, aplurality of shafts driven therefrom, a shaft driven by said shafts,brake members on each of said plurality of shafts brake membersengageable with said brake members a connecting member for the lastmentioned brake members, a link on said connecting member and anoperating member connected to said link.

4. Apparatus of the class described, having a first shaft a secondshaft, intermeshing gear Wheels driven from said shafts, one of saidgear Wheels slidable relatively to the other, and means to fasten saidshafts at angular adjustment.

5. Apparatus of the class described having a shaft, a shaft member, agear Wheel on said shaft a slidable gear member driven from said shaftmember in mesh With said gear Wheel, one of said members having a grooveand the other having a projection and means to fasten said shaft andshaft member at angular adjustment.

In testimony whereof I affix my signature in presence of two Witnesses.

MORRIS RAKOIVSKY.
